SEGIFIGATION forming part of Letters Patent o. 665,886, ldated January 1 5, 1901.

Application filed February 26, 1900. Serial No. 6.630. (No model-J which form n pan-t of this specificntion.`

VThis invention relates to cesings or pecl(- ings for Ariesien wells, and has for one object 'to provide nn improved casing which is con-- struc-,ted to permit of the inflow of liquid for the entire length of the casing, so as to directly receive the liquid from the different strate through which the Well may pass, and thns niord s much grenier inlet than that nliorded by the open lower end ol" the casing. it is furthermore designed to provide the, casing with a-n improved arrangement of filtering medie, so that the liquid m ey be eliectively filtered before passing into the interior of the casing.

With these and other-Objects in View the present invention consists in the combination Y and arrangement of parts, as will be hereinafter more fullydescribed, shown in the accompanyingdrewings,nnd p-rticnlnrly pointed ont in the appended claims, it being understood that changes inthe form, proportion, eine, end minor details may be mede within the scope of the claims without departing from the spirit or sacrificing any of the ndentnges of the invention.

in the drawings, Figure l is at Vertical tional View of the improved casing applied to n, well. ci" the easing. Fig. 3 is e similar View of :t modified forni. of the cnsing. Fig. 4 is e detnil sections-tl elevation showing two sections ol the casing connected together;

Correspondingl parts in the sever-rtl ligures of the drawings nrc designated by like cintrnlcters of reference.

Referring to the drawings, l designates the bore of si, well which hns been formed by the, cnrth-nuger 2, that lies n stem 3, which is removztbly connected to the lower end of the operating-shalt 4 by ineens ol n scrcw-thrend- Fig. 2 is n transverse sectional View l ed collztr o. ttt-ing device, snch ns n. handle-bnr l5, by which been completed the shaft is turned in n reverse direction, so es to disconnect the shaft from the stom by ineens oll the screw-threaded coller 5, in Order that the enger and its comparatively short stem may be left in the bottom of the Well.

which is held against longill-udinnl movement by ineens of the opposite lixed collnrs or annuler flanges 8 and 9, so that the hond mary remnin `fixed 'with respect to lhe rotary movement of' the slnrft during the Operation thereof. s

As ihe heed 7 solid or `imperforsttc and snugly fits the lower end of the tubular cesing, which latter ternlinntes short of the npper side of the auger, snid `head also forms n. closure for the open lower cndolf the casing, so este exclude the dirt :ind borings from the l ringer.

The present form of casing l0 surrounds the shaft nndvsnugly embraces thc heztd 7, to theperipheryof which it is connected by men-ns ol' suitable fnstenings ll, so that the cnsing may remain iixcd against rotation dur ing the operation of the slntfl and nl, the sanne time will be carried downwzn-dly with the ringer.

rlhe present casing is formed in sections, :is usuel, nud ench section is formed from n single length of sheet mattei-inl, preferably metri-l, which is bent into tubular form, with its opposite longitudinal edges overlrtppcd, :is plainly shown in Figs. 2 and 3 of thedrnwings, said overlapped portions being lnstened by the respective edges only of the sheet of metal. )By this fornnition of tnbnlztr casing nn overl lapped joint is provided for the entire length of the section, end through this joint or 1ongitlnlinelly-coutinuons inlet the liquid-moy enter the interior ci' the cztsing. 'lhus the casing may receive the liquid from sever-:tl strzttzt through which it nntypnss,'nnd thereforciho casing lntsn, more extensive inlet than that tlliorded by the usunl open lower end of the casing.

in order that thc liquid nnty bo liltercd lJo- The shaft has n, suitable operthe enger may be rotated. After the well has Intermedia-te of the opposite ends of thc steine there is provided n swiveled head 7,-

rivets or the like l2, which nre nrrztngcd-ntfore entering the interior of the casing, the outer or both overlapped portions of the casing maybe corrugated, as shown at 13 in Fig. 3, so as to form a plurality of pockets or recesses 14:, ,which extend for the entire lengthofthe section. In some or all of these pockets there is placed suitable filtering material 15, through which the liquid must pass to enter the casing and is thereby effectively filtered. Y

It will of course be understood that the a'uger is of greater diameter than the casing, so

-that the latter may pass downwardly without interfering with the operation of the auger, and additional sections of easing are secured to the uppermost casing, as indicated in Fig. 4, as it becomes necessary on account of the sinking of the auger.

Whatis claimed is- 1. In a well-boring apparatus, the combination of anearth-auger, havin g a stub stem,a rotatable shaft operatively and removably connected to the stem, an annular head swiveled 'upon the stem intermediate of the auger and the shaft.

2. Ina well-boring apparatus, the combination of an earth-auger, havin ga stub ste m, a rotatableI shaft operatively and detachably connected to the stem, opposite annular, anges upon an intermediate portion of the stern, a

` head loosely receiving the stem and held between the flanges, and a tubular well-casing inclosing the shaft, terminating short of the auger, and snugly receiving the head within the lower end thereosaid head formingr a closure for the lower end of tliecasing, and fastenings driven through the casing and into the peripheralA edge of the head, whereby the latter and the casing are ixedly and perinanently connected and remain stationary, with respect to the rotary movement of the shaft.

3. A permanent tubular well-casing, having an overlapped longitudinal joint, the latter forming continuous inlet for the entire length of 'the casing.

4r. [i permanent tubular well-easing, havin a corrugated overlapped longitudinal Joint, the 'latter forming a continuous inlet for the entire length of the casing, and filter'- ing material hold within some or all of the corrugatious.

5. A permanenttubular weite-asing,formed from sheet metal, which is lient into tubular form, the opposite longitudinal edges thereof being overlapped, and rivets or analogous fastenings connecting the respective edges to the adjacent portions of the casing, the joint formed by the overlapped edges of the she-et metal alsoforming a continuousinlet.

6. A permanent tubular well-casing, formed from sheet metal, which is bent into tubular form, theo'pposite longitudinal edges of which are overlapped, one of the overlapped edge portions being corrugated longitudinally for its entire length, rivets or analogous fastenings connect-ing the respective edges to the adjacent portions of the casing, the joint formed by the overlapped edges ofthe casing, also forming a continuous inlet for the entire lengthof the. casing, and filtering material. held within some or all of the corrugations.
